Effects of abiotic factors on movements of pikeperch during pre-spawning and spawning season in a Baltic archipelago

The effects of temperature, water level and moon phase on the movements of pikeperch (Sander lucioperca) were studied during pre-spawning and spawning season from April to June. Trends in catches and temperature were removed with linear regression. Cross-correlation analysis showed that temperature...

Zusammenfassung:	The effects of temperature, water level and moon phase on the movements of pikeperch (Sander lucioperca) were studied during pre-spawning and spawning season from April to June. Trends in catches and temperature were removed with linear regression. Cross-correlation analysis showed that temperature change one and two days earlier had the strongest effect on catches. Close to the new moon, pikeperch catches increased, whereas changes in water level had no effects on movements.
